The Cisco
® Content Services Gateway - Second Generation (CSG2) provides intelligent network capabilities such as flexible policy management and charging based on deep packet inspection, as well as subscriber- and application-awareness capabilities that enable mobile operators to quickly and easily offer value-added, differentiated services over their mobile data networks. The CSG2 is the highly scalable, fault-tolerant solution that has been deployed by mobile operators worldwide to help them meet the demands of their rapidly growing mobile broadband services.

The Cisco CSG2 is an application deployed on the Cisco Service Application Module for IP (SAMI), which provides high-capacity parallel processing to the Cisco 7600 Series Routers (Figure 1). Together these technologies deliver the scalability and performance requisite for current and next-generation Mobile Internet solutions.

Cisco Mobile Internet

The Cisco CSG2 is part of Cisco's Mobile Internet portfolio of solutions and can readily interface to all the control elements in a mobile network, including multiple Radio Access Networks (RANs), back-end billing systems, policy control systems, content-filtering, and compression solutions. Mobile operators can install and deploy Cisco Mobile Internet solutions without disrupting any services.

Cisco has demonstrated the interoperability of the platform with many popular RAN solutions as well as authentication, authorization, and accounting (AAA); content billing; policy control, content filtering; and compression solutions, relieving mobile operators of the need to dedicate resources to ensure a smooth deployment. More than 100 mobile operators worldwide have deployed Cisco Mobile Internet solutions. In addition, Cisco's strong partnerships with top billing, policy, mediation, and filtering vendors provide an end-to-end content billing and filtering solution.

• Identifies and correlates users based on IP addresses obtained from AAA RADIUS flows or from an XML database

• Records subscriber access information and charging identification that can be provided to the billing system in conjunction with regular charge reporting, thus allowing charge differentiation based on access and offloading significant correlation load from the billing system

Open interface with multiple billing agents

• Standard, open base protocols are used to communicate with the billing mediation or billing devices

• Provides failover in the event that one of the billing systems becomes unavailable

• Provides robust reporting

Use of content for data mining

• Service providers can gather subscriber network, service, and content-usage data across their networks

• Providers can apply business intelligence to the collected information to better understand user transaction behaviors and apply that knowledge to marketing and partnership strategies

• Traffic patterns can also be analyzed for use in QoS plans

• Popular sites can be identified and approached with real data to justify opportunities for content-delivery hosting

Content filtering

• Provides support for dynamic content filtering in conjunction with Cisco partners

• Service providers can provide personal filtering based on blacklists and whitelists, allowing access to content deemed appropriate or on a paid-for basis

• 100 MB of map storage; total number of maps and matches vary by configuration

• 8192 policies

• 32 maximum active QS/BMA

• Up to nine Cisco CSG2s can be installed in a Cisco 7600 Series chassis

Performance:

• Up to 1,400,000 concurrent sessions per 1-GB SAMI 2.0 module

• Up to 4,750,000 concurrent sessions per 2-GB SAMI 2.0 module

• Up to 500,000 connected subscribers per 1-GB SAMI 2.0 module

• Up to 1.25 million connected subscribers per 2-GB SAMI 2.0 module

• Up to 4500 Advices of Charge (AOCs) per second

• Up to 7500 data plane Layer 7 transactions per second

• Up to 12,000 data plane Layer 4 transactions per second

Throughput:

• Throughput performance per Cisco CSG2 is up to 8 Gbps.
